dmaengine: Add note to dmatest documentation about supported channels
The documentation is not so clear for newbies in a sense of what type of the channels are supported by it. Clarify this by adding a note at the preamble of the documentation.

This small document introduces how to test DMA drivers using dmatest module.
|
||||
|
||||
.. note::
|
||||
The test suite works only on the channels that have at least one
|
||||
capability of the following: DMA_MEMCPY (memory-to-memory), DMA_MEMSET
|
||||
(const-to-memory or memory-to-memory, when emulated), DMA_XOR, DMA_PQ.
